What is HX?
HX is the essence of Hydro. It’s interwoven into every strand of Hydro’s story, from our products to our people, our engineering pedigree to our approach to business and problem-solving.
HX is a stamp of quality and a mark of our commitment to optimum process performance. A Hydro solution is tried, tested and proven.
There is no equivalent to Hydro HX.
Hydro runs a multidisciplinary R&D programme designed to expand the company's reach in the stormwater, wastewater, industrial and combined sewer overflow sectors of the water industry. The four-part programme consists of computer modelling with computational fluid dynamics (CFD), laboratory analysis, field verification and collaboration with industry experts and academic institutions; both in the UK and US.
Hydro conducts laboratory research out of its facilities in Clevedon, England and Portland, Maine, USA.
The Portland facility is the Hydro Group's centre for Water Quality analysis. This world class facility has the capacity to evaluate full-scale equipment at treatment flows in excess of 170 l/s (6 cfs).
The Clevedon facility is the centre for the Group's Water Quantity research. This facility is equipped with the most sophisticated flow measuring equipment that delivers accurate readings under the most turbulent of conditions.
Current and past collaborations have included Bristol, Cardiff , Exeter, and Liverpool John Moores Universities in the UK, and The Civil, Construction and Environmental Engineering Department at the University of Alabama and The Stormwater Center at the University of New Hampshire in the US.
Computational Fluid Dynamics (CFD) plays an important role in Hydro's customer service and R&D programme, and as such has invested heavily with this technology, building a dedicated server cluster and training. In addition to furthering Hydro's level of customer service and aiding the R&D programme, Hydro also uses its CFD expertise to advise leading regulatory agencies, industry experts and academic institutions in all water industries.
Hydro's researchers use CFD to evaluate and compare the performance of potential new product configurations. Hydro also applies CFD to projects with unusually complicated flow schemes in order to alleviate the risks of cavitation or uneven flow loading.
Hydro has become an internationally recognized expert in CFD technology. Through the use of CFD, Hydro was the first to uncover and demonstrate pollutant washout in stormwater treatment chambers - the phenomenon by which intense runoff flows cause enough turbulence to wash previously captured pollutants back into the water course.
Many of the technical papers authored by Hydro International's researchers have used CFD to predict and validate the performance of the company's innovative technologies.CFD
Chesapeake Bay Reg-U-Flo® Vortex Valve case study.
High density urban site needed onsite treatment and underground stormwater storage. Reg-U-Flo Vortex Valve eliminated 100% of the excess storage volume and reduced cost of storage system by over $150,000.
Columbus Water Works Storm King® with Swirl-Cleanse™ case study.
During heavy rain events the rapid influx of stormwater caused the city’s combined sewer overflows (CSOs) to overload — causing untreated water to flow directly into the Chattahoochee River.
Two CSO treatment facilities with 12 Storm King Overflow vortex separators coupled with filtration and disinfection have helped provided a cost effective, sustainable solution for the City of Columbus and saved an estimated $20-30 million in capital costs alone.
The project won Columbus Water Works the 2001 EPA Award for CSO Program Excellence.
Storm King helps CSO Mitigation in Saco, ME case study.
Untreated sewage overflowed into the Saco River during intense storm events so a 22-ft diameter Storm King was installed which was smaller, more economical and more efficient than conventional clarifier tanks.
Hydro SludgeScreen™ Protects Treatment Works from Rag in Margate and Broadstairs Case study.
Southern Water’s new £80 million wastewater treatment works for the Margate and Broadstairs catchment area needed to be constructed to meet the stringent European Urban Waste Water Directive.
The installation of four of Hydro International’s SludgeScreen™ screening units was essential to protect the treatment process from excessive incoming rag.
As well as bringing extensive environmental benefits to the area, it will help local beaches meet the European Bathing Water Directive and boost the tourist trade.
Replacing Fox Lake’s dated aerated grit removal system with Eutek HeadCell® case study.
Fox Lake’s existing aerated grit removal system was at the end of its useful life and needed to be replaced. The Eutek HeadCell® was able to be retrofit into the existing area while improving performance and also eliminate grit deposition in the grit basin which was very difficult to remove. The new Eutek HeadCell system was found to be 88% efficient overall.
